PurposePrior literature provides empirical evidence that financial performance improves for core remaining operations after a firm discontinues some of their operations. This study aims to examine whether the association between discontinued operations and future financial performance improvement is affected by a regulatory rule (i.e. Statement of Financial Accounting Standards 144 [SFAS 144]) that significantly altered the reporting requirements of discontinued operations. This study also examines whether the association is dependent on the profitability of the operations discontinued.Design/methodology/approachOrdinary least square regressions are used to test the association between discontinued operations and financial performance improvement, conditional on the profitability of operations discontinued in the pre-SFAS 144 and SFAS 144 regulatory regimes. Data on profitability of operations discontinued is hand-collected.FindingsResults suggest that firms experience improvement in financial performance following the reporting of discontinued operations in the pre-SFAS 144 era. Using hand-collected data on the profitability of operations discontinued, this research study also shows that improvement in performance is stronger for firms that discontinue loss operations compared to those that discontinue profitable operations.Originality/valueThis study explores the impact of regulatory change on the association between discontinued operations and future performance. Furthermore, unique hand-collected data is used to understand whether financial performance improvement is conditional on the profitability of the operations discontinued. Results documented in this paper should be of interest to investors, regulators and analysts in understanding the long-term strategic implications of discontinued operations.
目的先前的文献提供了经验证据,证明在公司停止部分业务后,核心剩余业务的财务绩效会有所改善。本研究旨在检验已终止业务与未来财务绩效改善之间的关联是否受到一项监管规则(即财务会计准则声明144 [SFAS 144])的影响,该规则显著改变了已终止业务的报告要求。本研究还探讨了该协会是否依赖于已终止业务的盈利能力。设计/方法/方法使用普通最小二乘回归来测试终止业务与财务绩效改善之间的关系,条件是在SFAS 144之前和SFAS 144监管制度下终止业务的盈利能力。已终止业务的盈利能力数据是手工收集的。研究结果表明,在sfas 144之前的时代,公司在报告终止业务后的财务绩效有所改善。利用手工收集的已终止业务的盈利能力数据,本研究还表明,与停止盈利业务的公司相比,停止亏损业务的公司业绩改善更强。原创性/价值本研究探讨了监管变化对已终止业务与未来绩效之间关系的影响。此外,使用独特的手工收集的数据来了解财务业绩的改善是否取决于已停止业务的盈利能力。本文记录的结果应该对投资者、监管机构和分析人员了解终止业务的长期战略影响感兴趣。

This paper aims to investigate the efficiency of different hedging strategies for an investor holding a portfolio of foreign currency bonds.,The simplest strategies of no hedge and fully hedged are compared with the more sophisticated strategies of the ordinary least squares (OLS) approach and the optimal hedge ratios found by the dynamic conditional correlation-generalised autoregressive conditional heteroskedasticity approach.,The sophisticated hedging strategies are found to be superior to the simple strategies because they lower the portfolio risk in domestic currency terms and improve the Sharpe ratios for multi-asset portfolios. The analyses also show that both the OLS and dynamic hedging strategies imply holding a limited carry position by being long in high-yielding currencies but short in low-yielding currencies.,The performance of multi-currency portfolios is examined using more realistic assumptions than in the previous literature, including a weekly frequency and a constraint of no short selling. Furthermore, carry trades are shown to be part of an optimal portfolio.
本文旨在研究投资者持有外币债券投资组合时不同对冲策略的效率。将最简单的无套期保值和完全套期保值策略与更复杂的普通最小二乘(OLS)策略和由动态条件相关-广义自回归条件异方差方法发现的最佳套期保值比率进行了比较。复杂的对冲策略优于简单的策略,因为它们降低了以本币计算的投资组合风险,提高了多资产组合的夏普比率。分析还显示,OLS和动态对冲策略都意味着持有有限的套息头寸,即做多高收益货币,做空低收益货币。本文使用比以往文献更现实的假设,包括每周频率和不卖空约束,对多货币投资组合的表现进行了检验。此外,套利交易被证明是最优投资组合的一部分。

Purpose - This paper aims to investigate whether the cyclicality of local real estate prices affects the systematic risk of local firms using a geography-based measure of land availability as a quasi-exogenous proxy for real estate price cyclicality. Design/methodology/approach - This paper uses the geography-based land availability measure as a proxy for the procyclicality of real estate prices and the location of a firm’s headquarters as a proxy for the location of its real estate assets. Four-factor asset pricing model (market, size, value and momentum factors) is used to examine whether firms headquartered in more land-constrained metropolitan statistical areas have higher systematic risks. Findings - The results show that real estate prices are more procyclical in areas with lower land availability and firms headquartered in these areas have higher systematic risk. This effect is more pronounced for firms with higher real estate holdings as a ratio of their tangible assets. Moreover, there are no abnormal returns to trading strategies based on land availability, consistent with stock market betas reflecting this local real estate factor. Research limitations/implications - This paper contributes to the literature on local asset pricing factors, the collateral role of firms’ real estate holdings and the co-movement of security prices of geographically close firms. Practical implications - This paper has important managerial implications by showing that, when firms decide on the location of their buildings (e.g. headquarters building, manufacturing plant and retail outlet), the location’s influence on systematic risk should be part of the decision-making process. Originality/value - This paper is among the first to use a geography-based measure of land availability to study whether the procyclicality of local real estate prices influences firm risk independent of the procyclicality of the local economy. Thus, both the portfolio formed and firm-level analyses provide a more direct evidence of the positive relation between the procyclicality of local real estate prices and firm risk.
目的-本文旨在研究当地房地产价格的周期性是否会影响当地企业的系统性风险,使用基于地理的土地可用性度量作为房地产价格周期性的准外生代理。设计/方法/方法-本文使用基于地理的土地可用性度量作为房地产价格顺周期性的代理,并使用公司总部的位置作为其房地产资产位置的代理。采用四因素资产定价模型(市场、规模、价值和动量因素)来检验总部设在土地约束更强的大都市统计区域的公司是否具有更高的系统风险。研究结果表明,在土地可得性较低的地区,房地产价格更具顺周期性,总部设在这些地区的公司具有更高的系统风险。这种影响对于房地产占有形资产比例较高的公司更为明显。此外,基于土地可用性的交易策略没有异常回报,这与反映当地房地产因素的股市贝塔值一致。研究局限/启示-本文对本地资产定价因素、公司房地产持有的抵押品作用和地理上接近的公司证券价格的共同运动的文献做出了贡献。实际意义-本文具有重要的管理意义,通过显示,当公司决定其建筑物的位置(例如总部大楼,制造工厂和零售店),位置对系统风险的影响应该是决策过程的一部分。原创性/价值——本文是第一批使用基于地理的土地可用性度量来研究当地房地产价格的顺周期性是否独立于当地经济的顺周期性影响企业风险的论文之一。因此,无论是投资组合的形成还是企业层面的分析,都为当地房地产价格的顺周期性与企业风险之间的正相关关系提供了更直接的证据。

The purpose of this study is to examine the influence of the readability of annual reports on firms’ ability to obtain trade credit from suppliers. Particularly, the authors conjecture that annual report readability helps firms obtain more trade credit from suppliers.,The authors use the Gunning Fog Index as the primary measure of annual report readability and the ratio of accounts payable to the book value of total assets as the measure of trade credit.,Results from the study of 4,754 firms during the 2004–2016 period indicate that suppliers extend more trade credit to firms with more readable financial reports. The authors’ results are robust to alternative measures of trade credit and annual report readability. The authors’ results remain robust when we control for firm fixed effects and potential endogeneity problems using the instrumental variable approach. A further test shows that the level of trade credit is higher for firms in business service industries, and that this relation is weakened when firms disclose less readable 10-K filings.,The authors’ findings provide new insight into the role of financial report readability in firms’ ability to obtain trade financing from suppliers. The authors’ results are also in line with the SEC’s encouragement that firms use plain English and easy language in financial reporting.
本研究的目的是检验年度报告的可读性对企业从供应商那里获得贸易信贷的能力的影响。特别是,作者推测年度报告的可读性有助于企业从供应商那里获得更多的贸易信贷。,作者使用Gunning Fog指数作为衡量年度报告可读性的主要指标,使用应付账款与总资产账面价值的比率作为衡量贸易信贷的指标。,2004-2006年期间对4754家公司的研究结果表明,供应商向财务报告可读性更强的公司提供了更多的贸易信贷。作者的研究结果与贸易信贷和年度报告可读性的其他衡量标准相比是稳健的。当我们使用工具变量方法控制企业固定效应和潜在内生性问题时,作者的结果仍然是稳健的。进一步的测试表明,商业服务业企业的贸易信贷水平更高,当企业披露可读性较差的10-K文件时,这种关系会减弱。,作者的研究结果为财务报告可读性在企业从供应商获得贸易融资能力中的作用提供了新的见解。作者的研究结果也符合美国证券交易委员会的鼓励,即公司在财务报告中使用通俗易懂的英语。

Are leases substitutes or complements to debt? Insights from an analysis of debt covenants 租赁是债务的替代品还是补充?来自债务契约分析的见解

The purpose of this study is to investigate the relationship between off-balance-sheet (OBS) operating leases and long-term debt by analyzing firms’ debt risk profiles measured by the constraints on firms in the financial ratios in their debt covenants.,This study determines debt risk profiles using three measures: the ex ante probability of covenant violation (Demerjian and Owens, 2016), firms in violation of debt covenants and firms close to covenant violations.,High-risk firms according to all three measures, on average, have a significantly lower level of operating leases, indicating that these firms use OBS leases as a substitute for long-term debt. Interestingly, for firms operating in industries in which leases are widely available, firms with a high probability of covenant violation have a significantly higher level of operating leases, indicating that these firms use OBS leases as a complement to long-term debt. Further analysis indicates that lease financing is less costly than debt financing for these firms.,Overall, evidence of this study indicates that firms facing financial constraints may attempt to lease more of their assets, but the availability of leasing is constrained by their debt covenant obligations and the strength of the leasing market in its industry.,This study identifies states in which risky firms may treat leases as either complements or substitutes for long-term debt, implying that the leasing decision relates to the availability of an active leasing market for a firm’s assets and the firm’s financial constraints. The findings of this study support recent research showing that debt and leases are complementary in the presence of counterparty risk providing insight into the paradoxical relationship identified in prior research between leases and long-term debt.
本研究的目的是调查表外(OBS)经营租赁和长期债务之间的关系,通过分析公司的债务风险概况,衡量公司在其债务契约中的财务比率的约束。本研究使用三种指标确定债务风险概况:违约的事前概率(Demerjian and Owens, 2016)、违约的企业和接近违约的企业。根据这三个指标,高风险公司的平均经营租赁水平明显较低,这表明这些公司使用OBS租赁作为长期债务的替代品。有趣的是,对于在租赁广泛可用的行业中运营的公司来说,违约概率高的公司的经营租赁水平要高得多,这表明这些公司使用OBS租赁作为长期债务的补充。进一步分析表明,对这些公司来说,租赁融资的成本低于债务融资。总体而言,本研究的证据表明,面临财务约束的公司可能会尝试租赁更多的资产,但租赁的可用性受到其债务契约义务和行业租赁市场实力的限制。本研究确定了风险公司可能将租赁视为长期债务的补充或替代品的状态,这意味着租赁决策与公司资产的活跃租赁市场的可用性和公司的财务约束有关。本研究的结果支持了最近的研究结果,该研究表明,在交易对手风险存在的情况下,债务和租赁是互补的,为之前研究中发现的租赁和长期债务之间的矛盾关系提供了见解。

Audit firm tenure and perceived audit quality: evidence from CEO incentive contracts 审计事务所任期与感知审计质量:来自CEO激励合同的证据

This paper aims to examine how compensation committees perceive audit quality as indicated by audit firm tenure. Using the contracting weight attached to earnings and cash flows in chief executive officer (CEO) compensation as proxy for the compensation committee’s perception of audit quality, the study examines whether compensation committees perceive performance metric informativeness as being affected by auditor tenure.,The paper regresses CEO cash compensation on accounting-based performance metrics and on interactions between auditor tenure and accounting-based performance metrics while controlling for other factors previously shown to affect CEO pay. Auditor tenure is measured using continuous and dichotomous variables.,Auditor tenure is associated with a reduced (positive) weight on earnings (operating cash flows), which suggests lower perceived audit quality as tenure lengthens consistent with the auditor closeness argument. This relation is asymmetric, i.e. the negative effect of longer auditor tenure on incentive contracting is more pronounced for positive earnings. The results are robust to using CEO total compensation as the compensation measure, as well as using level and change specifications.,The inability to control for audit partner tenure in assessing the effect of audit firm tenure on incentive contracting and the potential endogeneity between auditor tenure choice and incentive contracting are the main limitations of this study. Given the lack of information on US audit partner tenure, the study could not control for the audit partner tenure issue. However, the study has attempted to mitigate the endogeneity issue by using a Heckman selection model that includes in the first-stage a regression of auditor tenure on various firm, performance measure and CEO-related governance characteristics, based on existing models (Li et al., 2010).,Compensation committees view auditor tenure as an indicator of accounting quality in setting CEO pay. Further, long auditor tenure is perceived as detrimental to financial reporting integrity, particularly when earnings numbers suggest positive managerial performance and innovations.,This study provides empirical evidence that auditor tenure matters in setting executive pay. Further, this study shows evidence on the link between auditor tenure and audit quality from an internal user’s perspective. Prior studies have focused either on external users (investors, creditors) or on the preparer (using measures such as discretionary accruals or meet/beat analysts’ forecasts or forecast guidance).
本文的目的是研究薪酬委员会如何感知审计质量的审计事务所任期。利用首席执行官薪酬中与盈利和现金流相关的承包权重,作为薪酬委员会对审计质量感知的代理,该研究检验了薪酬委员会是否认为绩效指标的信息量受到审计师任期的影响。本文根据基于会计的绩效指标以及审计师任期与基于会计的绩效指标之间的相互作用,对CEO现金薪酬进行了回归,同时控制了之前显示的影响CEO薪酬的其他因素。审计师任期是用连续变量和二分类变量来衡量的。审计师的任期与盈余(经营性现金流量)的权重降低(正)相关,这表明随着任期的延长,审计质量的感知会降低,这与审计师的密切性论点一致。这种关系是不对称的,即较长的审计师任期对激励合同的负面影响对于正盈余更为明显。研究结果对CEO总薪酬作为薪酬度量,以及使用水平和变动规格具有鲁棒性。在评估审计事务所任期对激励性合同的影响时,无法控制审计合伙人任期以及审计师任期选择与激励性合同之间的潜在内生性是本研究的主要局限性。鉴于缺乏关于美国审计合伙人任期的信息,该研究无法控制审计合伙人任期问题。然而,该研究试图通过使用Heckman选择模型来缓解内生性问题,该模型基于现有模型,在第一阶段对不同公司的审计师任期、绩效指标和首席执行官相关的治理特征进行回归(Li et al., 2010)。薪酬委员会将审计师的任期视为制定CEO薪酬时会计质量的一个指标。此外,长期的审计师任期被认为不利于财务报告的完整性,特别是当盈利数字表明积极的管理绩效和创新时。本研究提供了经验证据,证明审计师的任期对高管薪酬的设定有影响。此外,本研究从内部使用者的角度显示了审计师任期与审计质量之间联系的证据。先前的研究要么集中在外部使用者(投资者、债权人),要么集中在编制者(使用诸如可自由支配的应计项目或达到/超过分析师预测或预测指导等措施)。

This paper aims to investigate the association between analyst forecast dispersion and investors’ perceived uncertainty toward earnings.,A new measure for investors’ expectations of earnings announcement uncertainty is constructed, using changes in implied volatility of option contracts prior to earnings announcements. Unlike other proxies of uncertainty, this measure isolates the incremental uncertainty regarding the upcoming earnings announcement and is a forward-looking measure.,Using this new proxy, this paper finds a significant negative correlation between analyst forecast dispersion and investors’ uncertainty regarding the upcoming earnings announcements. Further tests show that this negative correlation is driven by analysts’ private information acquisition rather than analysts; uncertainty toward upcoming earnings announcements. Additional cross-sectional tests show that this negative relationship is more pronounced in the subsample with lower earnings quality.,This paper helps to further the understanding of the information content of analyst forecast dispersion, particularly the ways in which they gather and produce private information and their incentives for so doing.,This paper introduces a new market-based and forward-looking proxy of earnings announcement uncertainty that should be useful in future research. This paper also provides original empirical evidence that analysts gather and produce an additional private information to the market when facing noisy signals and that their information reduces investors’ uncertainty toward upcoming earnings announcements.
本文旨在研究分析师预测离散度与投资者对收益的感知不确定性之间的关系。,利用收益公布前期权合约隐含波动性的变化,构建了一种新的衡量投资者对收益公布不确定性预期的指标。与其他不确定性指标不同,这项指标隔离了即将发布的盈利公告的增量不确定性,是一项前瞻性指标。,使用这个新的代理,本文发现分析师的预测离散度与投资者对即将发布的盈利公告的不确定性之间存在显著的负相关。进一步的测试表明,这种负相关性是由分析师获取私人信息而非分析师推动的;即将发布的盈利公告的不确定性。额外的横截面测试表明,这种负关系在收入质量较低的子样本中更为明显。,本文有助于进一步了解分析师预测分散的信息内容,特别是他们收集和产生私人信息的方式及其动机。,本文介绍了一种新的基于市场的、前瞻性的盈利公告不确定性代理,该代理应在未来的研究中有用。本文还提供了原始的经验证据,证明分析师在面对嘈杂的信号时会收集并向市场提供额外的私人信息,并且他们的信息减少了投资者对即将发布的盈利公告的不确定性。

Internal control and financial reporting quality of small firms 小企业内部控制与财务报告质量

The Dodd–Frank Act of 2010 exempts small, non-accelerated filers from compliance with Sarbanes–Oxley Act (SOX) Section 404b internal control audits. However, these firms are required to comply with other internal control regulations, namely, SOX Sections 302 and 404a, starting in 2002 and 2007, respectively. A small number of these firms also voluntarily adopted (and sometimes dropped) Section 404b during 2004-2010. The purpose of this study is to investigate the impact of a series of internal control regulations introduced by SOX on the financial reporting quality of small firms.,The research design for this study is empirical. Using unsigned and signed discretionary accruals as measures of financial reporting quality, the authors compare the financial reporting quality for adopters and non-adopters across four regulation regimes over the period 2000-2010: PRESOX, SOX 302, SOX 404a and SOX 404b.,The results indicate that most of the adopters and non-adopters benefited from SOX 302 and 404a compared with the PRESOX period. However, only the non-adopters gained incrementally when moving from SOX 302 to SOX 404a. Also, Section 404b benefited firms with material weaknesses, as well as firms without material weaknesses that had the lowest reporting quality, in the PRESOX period.,This study helps inform the important policy debate on whether to increase the threshold that is used for the SOX 404b exemption. It shows incremental benefits for firms that adopted Section 404b audits, even when they were complying with Section 302 and Section 404a. Consequently, extending the exemption to more companies would result in a loss of the reporting quality benefit of 404b.,This study contributes to the literature by focusing exclusively on non-accelerated filers and by examining differences across four regulation regimes over a long window compared to prior studies. It provides evidence that the financial reporting benefit of SOX 404b is not transitional, but rather extends for a few years even after some firms discontinued the 404b audits.
2010年的《多德-弗兰克法案》免除了小型非加速申报人遵守《萨班斯-奥克斯利法案》(SOX)第404b条内部控制审计的义务。然而,这些公司必须遵守其他内部控制法规,即SOX第302条和第404a条,分别从2002年和2007年开始。其中一小部分公司也在2004-2010年间自愿采用(有时甚至放弃)第404b条。本研究的目的是调查SOX引入的一系列内部控制法规对小企业财务报告质量的影响。,本研究的研究设计是实证的。作者使用未签署和签署的自由支配应计项目作为财务报告质量的衡量标准,比较了2000-2010年期间四种监管制度下采用者和非采用者的财务报告质量:PRESOX、SOX 302、SOX 404a和SOX 404b。,结果表明,与PRESOX时期相比,大多数采用者和非采用者受益于SOX 302和404a。然而,当从SOX 302转移到SOX 404a时,只有非采用者获得了增量收益。此外,第404b条使有重大弱点的公司以及没有重大弱点的报告质量最低的公司在PRESOX期间受益。,这项研究有助于为是否提高SOX 404b豁免门槛的重要政策辩论提供信息。它显示了采用第404b条审计的公司的增量收益,即使它们遵守了第302条和第404a条。因此,将豁免范围扩大到更多的公司将导致404b的报告质量效益损失。,这项研究专门关注非加速申报者,并在很长一段时间内检查了四种监管制度与先前研究的差异,从而为文献做出了贡献。它提供的证据表明,SOX 404b的财务报告效益并不是过渡性的,而是在一些公司停止404b审计后仍会持续几年。

This study aims to examine whether the pay gap between the chief executive officer (CEO) and non-executive employees affects the firm’s research and development (R&D) efficiency.,The dependent variable is the firm’s R&D efficiency, defined as a percentage increase in revenue from a 1-per cent increase in R&D spending. The main independent variable is the CEO-employee pay gap, defined as the ratio of annual total compensation for the CEO to the average of non-executive employees of the firm. The authors estimate fixed-effects models to examine the association between R&D efficiency and the pay gap between CEO and non-executive employees.,Results indicate a negative and significant association between R&D efficiency and CEO-employee pay gap, which suggests that a wider pay gap reduces employee motivation and effort, consistent with pay equity theory. We also find that the CEO-employee pay gap negatively moderates the relationship between employee pay growth and R&D efficiency,Recently enacted pay gap disclosure requirements mandated by the Dodd-Frank Act will make the disparity between CEO and non-executive compensation more salient. This study provides evidence of a firm outcome associated with that disparity.,This study is among the first to investigate the impact of the pay gap on R&D efficiency, a firm outcome not previously explored in the literature. This study also investigates CEO-employee pay gap’s role as a factor that moderates the effects of employee pay growth and institutional ownership on R&D efficiency
本研究旨在检验首席执行官(CEO)和非执行员工之间的薪酬差距是否会影响公司的研发效率。,因变量是公司的研发效率,定义为研发支出增加1%后收入的百分比增长。主要自变量是首席执行官员工薪酬差距,定义为首席执行官的年度总薪酬与公司非执行员工平均薪酬的比率。作者估计了固定效应模型,以检验研发效率与CEO和非执行员工之间的薪酬差距之间的关系。,研究结果表明,研发效率与CEO员工薪酬差距之间存在负相关,这表明更大的薪酬差距会降低员工的动机和努力,这与薪酬公平理论一致。我们还发现,首席执行官与员工的薪酬差距对员工薪酬增长与研发效率之间的关系具有负向调节作用。最近颁布的《多德-弗兰克法案》规定的薪酬差距披露要求将使首席执行官和非执行薪酬之间的差距更加突出。这项研究提供了与这种差异相关的坚定结果的证据。,这项研究是最早调查薪酬差距对研发效率影响的研究之一,这是文献中从未探讨过的确切结果。本研究还调查了CEO员工薪酬差距作为一个因素的作用,该因素调节了员工薪酬增长和机构所有权对研发效率的影响

PurposeThis study aims to examine the cross-market efficiency of the FTSE/MIB index options contracts traded on the Italian derivatives market (IDEM) during a period including the financial crisis between 1st October 2007 and 31st December 2012 using daily option prices.Design/methodology/approachTwo fundamental no-arbitrage conditions were tested: the lower boundary condition (LBC) and the put–call parity (PCP) condition while taking into account the role of transaction costs in mitigating the number of violations reported. Ex post tests of LBC and PCP revealed a low incidence of mispricing in this market. Furthermore, to check the robustness of the results obtained by the ex post tests, ex ante tests were applied to PCP violations occurring within a one-day lag.FindingsThe results showed a significant drop in the number of profitable arbitrage strategies. The findings obtained from all these tests generally support the cross-market efficiency of the Italian index options market during the sample period, though some violations were occasionally reported. Overall, the number and monetary value of the violations reported declined during the post-financial crisis period compared to those during the financial crisis period.Research limitations/implicationsThis study can be extended to test the relationships between arbitrage profitability and other factors such as the moneyness (in the money, out of the money, at the money) of options and the maturity of options. Options market efficiency tests can be conducted such as call and put spreads, box spreads and put/call convexities (butterfly spreads).Originality/valueThere are several factors that influenced the decision to test the Italian index options market. First, the limited number of studies conducted on this market. Second, the fact that the two main studies on this market are relatively old, which makes it interesting to test the efficiency of this market with respect to a new set of data, taking into account the introduction of the Euro and the impact of the recent financial crisis on this market and whether the market efficiency hypothesis holds during the period of crisis. Third, it is important to consider the effect of the new rules applied to this market.
目的本研究旨在使用每日期权价格检验2007年10月1日至2012年12月31日金融危机期间在意大利衍生品市场(IDEM)交易的富时/MIB指数期权合约的跨市场效率。设计/方法/方法测试了两个基本的无套利条件:下限条件(LBC)和看跌期权平价(PCP)条件,同时考虑了交易成本在减少报告违规数量方面的作用。LBC和PCP的事后测试显示,该市场的错误定价发生率较低。此外,为了检查事后测试结果的稳健性,对一天内发生的PCP违规行为进行了事前测试。结果显示,盈利套利策略的数量显著下降。从所有这些测试中获得的结果通常支持样本期内意大利指数期权市场的跨市场效率,尽管偶尔会报告一些违规行为。总体而言,与金融危机期间相比,金融危机后期间报告的违规行为的数量和货币价值有所下降。研究局限性/含义这项研究可以扩展到测试套利盈利能力与其他因素之间的关系,如期权的货币性(货币内、货币外、货币内)和期权的到期日。期权市场效率测试可以进行,如看涨和看跌价差、箱差和看跌/看涨凸度(蝶差)。独创性/价值有几个因素影响了测试意大利指数期权市场的决定。首先,对这个市场进行的研究数量有限。其次,关于这个市场的两项主要研究都相对较旧,这使得在考虑到欧元的引入和最近金融危机对这个市场的影响,以及市场效率假说在危机期间是否成立的情况下,用一组新的数据来测试这个市场的效率变得有趣。第三,重要的是要考虑适用于这个市场的新规则的效果。
